2 contain a distorted octahedral [MnN6] core with two trans-disposed NCS− ions. The L1 ligand, 1 and 2, together with four known homologous Mn(II) complexes, trans-[Mn(L3-L6)2(NCS)2] (3–6) (3, L3 = 3-(p-methoxyphenyl)-4-(p-chlorophenyl)-5-(2-pyridyl)-1,2,4-triazole; 4, L4 = 3-(p-methoxyphenyl)-4-(p-bromophenyl)-5-(2-pyridyl)-1,2,4-triazole; 5, L5 = 3-(p-chlorophenyl)-4-(p-methylphenyl)-5-(2-pyridyl)-1
摘要 两种新的 Mn(II) 配合物,trans-[Mn(L1-L2)2(NCS)2] (1-2) 与三芳基三唑 (1, L1 = 3-(p-bromophenyl)-4-phenyl-5- (2-吡啶基)-1,2,4-三唑;2, L2 = 3,4-双(对甲基苯基)-5-(2-吡啶基)-1,2,4-三唑),已合成并通过元素分析、FT-IR、ESI-MS 和单晶 X 射线晶体学进行结构表征。晶体学研究表明,1 和 2 都包含一个扭曲的八面体 [MnN6] 核心和两个转置的 NCS− 离子。L1 配体 1 和 2,连同四种已知的同源 Mn(II) 配合物,反式-[Mn(L3-L6)2(NCS)2] (3–6) (3, L3 = 3-(p-甲氧基苯基)-4-(对氯苯基)-5-(2-吡啶基)-1,2,4-三唑;4,L4 = 3-(对甲氧基苯基)-4-(对溴苯基)-5-(2 -吡啶基)-1,2,4-三唑;5,L5
